PORTABLE PUMPING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 494,221, dated March28, 1893.

Application filed March 8, 1892. Serial No. 424,218. (No model.)Patented in England August 26, 1890, No. 13,418 in France June 16, 1891,N0.214,211; in Belgium June 16,1891, No. 95,292; in India October 7.1891, No. 200,9.ndin Austria-Hungary October 10, 1891.

To all whom it may concern:

Be it known that I, DONALD NOBLE, a subject of the Queen of GreatBritain, residing at Leeds, in the county of York, England, haveinvented new and useful Improvements in Portable Pumping Apparatus, (forwhich I have obtained Letters Patent in England, No. 13,418, datedAugust 26, 1890; in France, No. 214,211, dated June 16, 1891; inBelgium, No. 95,292, dated June 16, 189]; in Austria Hungary, datedOctober 10, 1891, and in In dia, No. 200, dated October 7, 1891,) ofwhich the following is a specification. This invention has reference tothat class of portable and other pu mping apparatus such as is describedin the specifications accompanying my applications for United States ofAmerica Letters Patent, Serial Nos. 405,852, and 424,217. Its object isto construct and arrange the pumping mechanism in as small a compass aspossible in a casing provided with a divided top to act as pedals, saidpedals being revolubly fitted on to the outward case ing for putting thepump piston or pistons in motion by means of a suitable arrangement oflevers. The casing also acts as a platform on which the operator standsfor actuating the pedals with the heels of his feet. I attain theseobjects by mechanism illustrated in the accompanying drawings in which:5

Figures 1, 2, and 3, are respectively a side elevation (with side ofplatform removed), an end elevation (with end of platform removed), anda plan (with portionsof the top of platform and of the pedals removed)ofpumping apparatus with cylinderor pump barrel made in two portions andoperated by compound levers. Figs. 4 and 5 are respectively a front andend elevation of compound levers. Figs. 6 and 7 are respectively asectional elevation and plan of valve box; Fig.8 an arrangement ofvalves applied to each end of the pump barrel.

A is a box like platform on which the bather or operator stands. Theplatform may be made of any desired material, such as sheet brass,copper, zinc, or the like, or of wood lined when required with thinbrass, or

' other material, but I prefer to make it of thin sheet brass, say aboutone sixteenth of an quire.

valve box, the brush or rose and nozzle, toilet inch in thickness andwatertight. A conven- 5o ient shape for the platform is rectangular andits size may he, say about eleven inches long by nine inches wide bythree inches in depth, but these dimensions (as well as the shape) maybe altered or varied as circumstances re- As for instance, when requiredfor military purposes, the platform may be made say about eight incheslong by four inches in width by two inches and three fourths of an inchin depth, that is as regards the width about one half of the size asshown at Figs. 1, 2, and 3, but at the same time possessing all theadvantages (for pumping purposes) of the larger size owing to extensionpieces (folding or fixed) being provided to which pedals D. D (hinged atthe toes) may be attached for operating purposes.

The platform A is of such a size, or if preferred it may be divided intoany number of compartments for receiving the double acting 7o pump andits actuating mechanism, the valve box, the flexible tube or tubes whichmay be packed away without uncoupling it or them from the inlet andoutlet portions of the requisites, and any other necessary or desiredarticles.

The platform A is provided with either a hinged, sliding or removablelid a. In the drawings the lid is shown divided into three portions. Thecentral portion is removable and the two outer portions may be hinged tothe side a of the platform or jointed to a rod running parallel to oneof the sides of the platform and mounted on bearings within the same soas to form pedals D. D. When the portions which form the pedals aredisconnected from the levers (to be hereinafter de- A scribed) employedfor actuating the piston o. c and are closed they complete the coveringportions of the platform. The pedals mayor may not be armed with piecesof wood, cork, P or other suitable nonconducting material (1 ThepedalsD. D are connected to levers employed for actuating the pistons 0,0 by brackets 01 d (shaped something like an inverted triangle) mountedin bearings d d respectively formed on or attached to the underside ofeach pedal as shown for purposes to be hereinafter described.

The pump barrel 0. (which with the piston actuating mechanism isinclosed within the platform) may be either formed in one piece sayabout seven inches long by two inches in diameter or in two portionsbi-partite, arranged say about two inches and three fourths ,of an inchapart. Each portion of the barrel may be about two inches and threefourths of an inch in length by about two inches diameter. The pumpbarrels are shown placed horizontally within the platform A parallel, ornearly so with the side a but in some cases when the barrel is made intwo portions it may be found advantageous to arrange the said portionsat right angles to the side a and respectively parallel or nearly sowith the ends a a Within the barrel 0, are mounted the pistons c, 0connected together by a single rod 0 to form a double acting pump,butwhen the two portions of the barrel 0 are arranged parallel or nearly sowith the ends a a then separate piston rods will be required. The barrel0. is provided with ends or covers 0 0*" to which the tubes H. H, may berespectively attached. 7

A reciprocating motion is imparted to the pistons c 0 from the heels ofthe operators feet through the pedals D. D and brackets d d, which arejointed by the trunnions d in the bearings d d on the underside of thepedals, and compound vertical and horizontal levers E, E and G as atFigs. 1 and 4. It will be readily understood that motion may be impartedto pistons by the pedals through pendants (fixed to the underside of thepedals) and a simple horizontal lever fulcrumed at or about its centerand shaped somewhat like a double bell crank lever is pivoted to thebottom of the platform with its front end raised to the level of thecenter of the pump barrel. In order to make the platform on which theoperator stands as shallow as possible and at the same time to obtainthe longest stroke of the pistons with the smallest movements of thepedals, I prefer employing the arrangement of compound vertical andhorizontal levers shown in the drawings in which the triangular shapedor double bell crank lever E, is mounted vertically in suitable bearings6 e attached to the bottom of the platform. The ends e e are enlargedand on these a horizontal lever E carried by trunnions in bearings e ofthe same bracket in which the bearings e are formed operates, while onthe enlarged end a of the vertical upright e is provided a pin e whichworks in a slot 6 of a pendent lever G fulcrumed on pin e carried bybrackets ar on the top of the platform.

The lower end e of the lever G passes through a slot formed for itsreception in the enlarged portion 0 of the piston rod. At Figs. fland 5I have shown a side elevation and an end elevation of levers E, E and G.The lower end of each bracket 61 d is bifurcated and made to work in agroove e formed for its reception in the horizontal lever E. When it isrequired to disconnect the pedal or pedals from the lever E, one or bothpedals may be raised until the bifurcated end or ends of the bracket orbrackets is or are clear of the lever; when each bracket may be turnedon its trunnions until it is parallel or nearly so with the underside ofthe pedal. The pedals may then be closed on thetop of the platform.

By jointing the brackets 01 d to the pedals D. D as herein described andconnecting them to lever E provision is thereby made for overcoming thefriction of the working parts as much as possible and at the same timepermitting of a direct (or nearly so) action being imparted to lever Efrom the pedals although said lever and pedals may be arranged to workat right angles to each other.

By the above arrangement of horizontal and vertical levers a'very smallmovement of pin e (in the slot 6 of pendent lever G) say about threeeighths of an inch, and of the outer or heel ends of the pedals, (sayabout seven eighths of an inch) will cause the pistons c c to travelabout an inch and a quarter, or

more. 7

To the inside of the barrel 0 are attached the tubes H, H communicatingat one end with the interior of the barrel (or when preferred theconnection may be made in the centers of the ends or covers 0 0 and attheir other ends with a valve box I placed between them, at or about thecenter of the barrel. The valvebox is divided at its center by a plate'5 to form two compartments or tubes z" i communicating with a centralinlet and outlet i 1' and respectively with the tubes H, H. In each ofthe tubes 2" v? are fixed two valve-seats i i and '5 i provided withindia rubber, metal, or other suitable ball valves 71 1' 43 71 and apiece of perforated zinc or other metal to prevent the valves fromrising too high. The communications between each of the compartments ortubes z" t and tubes II. II is midway between the valve seats as shown.

It will be readily understood that when preferred the above describedfixed pipes may be dispensed with, and corresponding passages with valveseats formed therein or cast on the barrel or on the ends or covers 0 '0as shown at Fig. 8. To the central inlet and outlet pipes t i isrespectively attached a piece of india rubber or flexible tubing of anysuitable length, that for the inlet being armed with an ordinary nozzle,and the outlet with or without a rose, or with a brush and rosecombined. The flexible tube provided with a nozzle may be placed in abucket or other receptacle containing hot or cold water and the othertube which is armed with the rose held by the operator. When pedal D isdepressed the pistons will be moved to the end 0*" of the barrel. At thesame time a vacuum will be formed at the end c which opens valves 2'closes 11 and draws water up out of the bucket into compartment i alongthe tube H and from thence into the space at the right hand of thebarrel 0. During the motion of the piston D at the end o of the barrel,any water that has been previously drawn up into that end of the barrelis driven along tube H into compartment 1" closing valve 2 and opening2' and forcing the water onto the bather, animal, or other article, orobject. A similar action is obtained when the other pedal is depressedonly the action of the valves is reversed.

One or more air vessels of ordinary construction (with or without ballvalves) may when required be combined with the pumping apparatus forinsuring a regular and constant supply of water being delivered from thepump. Any kind of self feeding brush or rose, or nozzle through whichWater may be forced by the herein described pumping apparatus may beemployed which permits of motion for actuating the pistons beingimparted to the pedals D. D by the heels of the operators feet as hestands upon the platform and balances himself upon his toes.

When the above described pumping apparatus is employed for bathing orwashing the human body it may be used with an ordinary bath or tray.When the bathing operations are completed the bath or tray may beemptied, (while the bather is drying himself) by reversing the positionof the'tubes thereby converting the outlet tube into the inlet, and theopposite tube into the outlet. But when the pumping apparatus is usedfor washing or bathing, horses, dogs, or other animals, carriages,windows, watering or sprinkling, gardens, flowers, plants or for likepurposes, I find it advantageous to place it within a receptaclecontaining water whereby the pumping certained the nature of my saidinvention and apparatus audits water supply may be read- 40 ily removedfrom one place to another.

I would have it understood that although I have described the abovearrangements of pumping apparatus as being applicable for pumping wateryet it may also be used for pumping, raising and ejecting any otherliquids that will not destroy or corrode its component. In some casesand when desired one or more vertical or horizontal pumps connected to avalve box such as I may be mounted either upon a platform such as A orwithin water receptacleand operated by pedals and mechanism such asherein described.

Having now particularly described and asin what manner the same is to beI declare that what I claim is- In a portable pump the combination ofthe box A containing the horizontal acting pump 0, the piston rod 0 forsaid pump, the vertical lever G pivoted at its upper end and connectedatits lower end with the said piston rod, the horizontal bent leverEmounted within said box A, the upright arm 6 rigidly connectedwith saidlever E and pivotally con- 65 nected with said lever G at or near itscenter, the horizontal lever E bearing on the free ends of the lever Eand the brackets d d connected to said hingedcovers D, D ,and bearing ator near the ends of said lever E, substantially as set forth.

In testimony whereof I have hereunto signed my name to thisspecification in presence of two subscribing witnesses.

DONALD NOBLE.
